• Main Ingredients: Lotus root (renkon), miso, powdered mustard (karashi), oil.

How It’s Eaten / Served

*Karashi renkon* is typically sliced into rounds, about 5 to 10 millimeters thick, so you can see the distinctive pattern that resembles the nine-star crest (kuyo-mon) of the Hosokawa clan. It’s usually eaten as is, and some people enjoy it with a touch of soy sauce or mayonnaise. Interestingly, folks have also come up with creative ways to enjoy it, like using it in croquettes, sandwiches, or even burgers. The mustard flavor is said to pair surprisingly well with bread, kind of like a Japanese take on mustard.

Cultural Background and Preservation

Kumamoto Prefecture is a major producer of lotus root in Japan. *Karashi renkon* has a fascinating history connected to the Hosokawa clan. Back in 1632, Lord Tadatoshi Hosokawa, the first lord of the Higo Hosokawa domain, was often in poor health. A worried monk from Rakanji Temple, Gen-taku Oshō, sought a nutritious food for him. Knowing that lotus root grew abundantly in the swampy areas of Kumamoto and was known for its blood-boosting properties in traditional medicine, he wanted Lord Tadatoshi to eat it. However, the lord refused, considering lotus root “impure” because it grew in mud. So, the monk devised a plan: he filled the holes of the lotus root with a mixture of miso and Japanese mustard, coated it in a batter of wheat flour, broad bean flour, and egg yolk, and then deep-fried it. The spicy kick of the mustard worked wonders! Lord Tadatoshi enjoyed it so much that it became a regular part of his diet, and his health improved significantly. The round slices of *karashi renkon* also resembled the Hosokawa clan’s nine-star crest. Lord Tadatoshi valued this dish and kept its preparation method a secret until the Meiji Restoration. This is why *karashi renkon* is still primarily produced and enjoyed in Kumamoto Prefecture. Today, it’s a popular side dish, a great accompaniment to drinks, and an essential part of New Year’s *osechi ryori* (traditional New Year’s food). You can find it not only in specialty stores but also in local supermarkets and souvenir shops, as well as on the menus of local restaurants and izakayas (Japanese pubs). Many establishments use lotus root from local contract farmers, and some specialty stores even grow their own.
